Description

Technical Field

[0001] This invention relates to the field of cable cutting technology, specifically a cutting device for processing carbon fiber ropes. Background Technology

[0002] Carbon fiber ropes are widely used in aerospace, sporting goods, and industrial robotics due to their superior properties such as high strength, high modulus, corrosion resistance, and light weight. In subsequent processing, carbon fiber ropes often need to be cut to specific lengths.

[0003] Currently, carbon fiber ropes are mostly cut using methods such as abrasive wheel cutting, shearing, or ultrasonic cutting. However, carbon fiber ropes are composed of thousands of extremely fine fiber bundles twisted together, resulting in a loose structure. The main technical challenges during cutting are as follows: First, only one rope can be cut at a time, making simultaneous cutting of multiple ropes inefficient. Second, because the clamping mechanism holding the rope is fixed in position during cutting, it cannot be further tightened, leaving the rope loose and hindering cutting. Third, during the cutting process, fibers from the rope easily adhere to the cutting tool; if not cleaned promptly, this affects subsequent cuts. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a cutting device for carbon fiber rope processing, which solves the problems of low cutting efficiency, inability to further tighten the rope, and easy adhesion of broken fibers to the cutting tool.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A cutting device for processing carbon fiber rope includes a base, a rope-releasing mechanism on one side of the base for simultaneously releasing multiple strands of carbon fiber rope, a frame connected to the other side of the base, a base fixed below the frame on the base, a movable seat connected to the base via an elastic reset member, a limit block fixed on the base, the limit block located below the movable seat and maintaining a distance from the movable seat, a support plate detachably connected to the top surface of the movable seat, specifically, the two sides of the support plate are connected to the movable seat by screws; the top surface of the support plate has several V-grooves, a lifting mechanism is mounted on the frame, the output end of the lifting mechanism is connected to a lifting seat, a pressure plate detachably connected to the bottom surface of the lifting seat, specifically, the two sides of the pressure plate are connected to the lifting seat by screws; the bottom surface of the pressure plate has several V-shaped pressure heads that match the V-grooves and protrude outwards. The carbon fiber rope can be pressed into the V-grooves by the V-shaped pressure heads.

[0006] The movable seat has a cutting table on the side facing the rope-releasing mechanism. The cutting table is located below one side of the V-groove. The lifting seat has a lifting lug on the side facing the rope-releasing mechanism. A first hydraulic cylinder is installed on the lifting lug. The telescopic end of the first hydraulic cylinder is connected to a lifting block. A blade plate is detachably connected to the bottom surface of the lifting block. Specifically, the two sides of the blade plate are connected to the lifting block by screws. The blade plate is located above the cutting table. By lowering the blade plate and cooperating with the cutting table, the carbon fiber rope can be cut.

[0007] The lifting block has an air duct along its long side. An air inlet pipe connected to the air duct is attached to the top surface of the lifting block. Several air outlets connected to the air duct are located at the bottom of the lifting block, and these outlets are inclined towards the blade plate. The air inlet pipe is connected to an external air compressor via a pipe. The air compressor supplies high-pressure gas to the air inlet pipe, which is then sprayed onto the blade plate through the air duct and air outlets, thereby blowing off the broken fibers on the blade plate.

[0008] Preferably, the rope-releasing mechanism includes a rope-releasing frame mounted on a base, a rope-releasing wheel rotatably connected to the rope-releasing frame via a rotating shaft, a reduction motor mounted on one side of the rope-releasing frame, a drive wheel connected to the motor shaft of the reduction motor, and a driven wheel connected to one of the rotating shafts. The drive wheel and the driven wheel are connected by a transmission belt. The rope-releasing wheel has several annular grooves, the same number as the V-grooves, and each annular groove is wound with carbon fiber rope. When the reduction motor is started, the rope-releasing wheel is driven to rotate through the cooperation of the drive wheel, the transmission belt, and the driven wheel, thereby releasing multiple strands of carbon fiber rope simultaneously.

[0009] Preferably, the base is equipped with an anti-rebound mechanism near the frame. The anti-rebound mechanism includes a support base, a crossbeam, a second hydraulic cylinder, and a fixing plate. The support base is fixed to the base, the crossbeam is connected to one side of the frame, the second hydraulic cylinder is mounted on the crossbeam, and the extension end of the second hydraulic cylinder is connected to the fixing plate. The bottom surface of the fixing plate is serrated, and the fixing plate is located above the support base. Before cutting, the second hydraulic cylinder extends, causing the fixing plate to descend and press the carbon fiber rope tightly against the support base. After the rope is cut, it will not spring back, thus facilitating the subsequent pulling of the rope end back into the V-groove.

[0010] Preferably, two guide frames are connected on the base between the rope feeding frame and the support base, and guide rollers are rotatably connected above the two guide frames. The two guide rollers are set at different heights and guide the carbon fiber rope to the space between the fixed plate and the support base.

[0011] Preferably, the elastic reset component includes at least one pair of guide posts and a compression spring sleeved on the guide posts; the lower end of the guide post is fixed to the base, the upper end passes through the movable seat, and the upper end of the guide post is connected to a limit plate to prevent the movable seat from falling off; the compression spring is supported between the base and the movable seat, and the movable seat is lifted up in the normal state by the compression spring. When the lifting seat descends, the pressure head presses down on the movable seat, and the movable seat sinks slightly at the same time, squeezing the compression spring, so that the carbon fiber rope is clamped under a slightly tensile state, further preventing uneven cuts caused by rope slack during cutting.

[0012] Preferably, the lifting mechanism includes a third hydraulic cylinder mounted on the frame and a guide rod slidably connected to the top frame. The telescopic end of the third hydraulic cylinder and the lower end of the guide rod are both connected to the lifting seat. By controlling the extension of the third hydraulic cylinder, combined with the cooperation of the guide rod, the lifting seat can be raised and lowered stably.

[0013] Preferably, at least two guide rails are installed on the lifting base below the lifting lugs, and a sliding groove is provided on one side of the lifting block, which is slidably connected to the guide rails through the groove. The sliding connection of the lifting block to the guide rails provides guidance and stability, improving the stability of the lifting block's movement.

[0014] Preferably, the frame has a notch to accommodate the passage of the first hydraulic cylinder. When the lifting seat is raised or lowered vertically, the first hydraulic cylinder moves within the notch, thereby preventing the frame from affecting the first hydraulic cylinder.

[0015] Preferably, a control cabinet is provided on one side of the machine base, and a PLC controller is installed inside the control cabinet. A start button and control buttons are installed on the control cabinet. The first hydraulic cylinder, the second hydraulic cylinder, the third hydraulic cylinder, the geared motor, the start button, and the control buttons are all electrically connected to the PLC controller. The PLC controller contains a control program. The start button is used to turn on the power, and there are multiple control buttons, which are used to control the operation of the first hydraulic cylinder, the second hydraulic cylinder, the third hydraulic cylinder, and the geared motor, respectively.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) By combining the V-shaped pressure head and the V-shaped groove, multiple ropes can be positioned at once, and then the fixed ropes can be cut by the blade, thus cutting multiple ropes at the same time and improving the cutting efficiency.

[0017] (2) During cutting, the movable seat is pressed down by the pressure head. Under the action of the elastic reset component, the movable seat sinks slightly in sync, so that the carbon fiber rope is clamped under tension and tension, preventing uneven cuts caused by rope slack during cutting.

[0018] (3) During the cutting process, high-pressure gas enters through the air inlet pipe and is sprayed onto the blade through the air duct and air outlet, thereby blowing off the broken fibers on the blade. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-6A cutting device for processing carbon fiber rope includes a base 1, with a rope-releasing mechanism on one side of the base 1, which simultaneously releases multiple strands of carbon fiber rope. The rope-releasing mechanism includes a rope-releasing frame 19 mounted on the base, a rope-releasing wheel 20 rotatably connected to the rope-releasing frame via a rotating shaft, a reduction motor 21 mounted on one side of the rope-releasing frame, a drive wheel 22 connected to the motor shaft of the reduction motor, and a driven wheel 23 connected to one of the rotating shafts. The drive wheel 22 and the driven wheel 23 are connected by a transmission belt. The rope-releasing wheel 20 has several annular grooves, the same number as the number of V-grooves, and each annular groove contains a strand of carbon fiber rope. Starting the reduction motor 21 drives the drive wheel 22 to rotate. Through the cooperation of the drive wheel 22, the transmission belt, and the driven wheel 23, the rope-releasing wheel 20 rotates, thereby simultaneously releasing multiple strands of carbon fiber rope.

[0022] On the other side of the base 1, a frame 2 is connected. A base 3 is fixed on the base 1 below the frame. A movable seat 4 is connected to the base 3 via an elastic reset member. A limit block 5 is fixed on the base 3, located below the movable seat 4 and maintaining a distance from it. A support plate 6 is connected to the top surface of the movable seat 4 via screws. The top surface of the support plate 6 has several V-grooves 7, each capable of supporting one carbon fiber rope. The support plate 6 is replaceable to accommodate ropes of different diameters. The elastic reset member includes at least one pair of guide posts 30 and a compression spring 31 sleeved on the guide posts. The lower end of the guide post 30 is fixed to the base 3, and the upper end passes through the movable seat 4. A limit plate 32 is connected to the upper end of the guide post 30 to prevent the movable seat 4 from falling off. The compression spring 31 supports the movable seat 4 between the base 3 and the movable seat 4, allowing the movable seat 4 to be lifted in its normal state. When the movable seat 4 is pressed downward, the movable seat 4 sinks slightly and compresses the compression spring 31. After the movable seat 4 contacts the limiting block 5, the movable seat 4 will not continue to move downward due to the cutting pressure, thus improving the stability during cutting.

[0023] A lifting mechanism is installed on the frame 2, and the output end of the lifting mechanism is connected to a lifting seat 8. The lifting mechanism includes a third hydraulic cylinder 33 mounted on the frame and a guide rod 34 slidably connected to the top frame. The extension end of the third hydraulic cylinder 33 and the lower end of the guide rod 34 are both connected to the lifting seat 8. By controlling the extension of the third hydraulic cylinder and cooperating with the guide rod, the lifting seat can be raised and lowered stably.

[0024] The bottom surface of the lifting seat 8 is connected to a pressure plate 9 by screws. The bottom surface of the pressure plate 9 is provided with several V-shaped pressure heads 10 that match the V-shaped grooves and protrude downwards. The V-shaped pressure heads 10 press the carbon fiber rope tightly into the V-shaped grooves 7, thereby keeping the rope stable. In addition, the pressure plate 9 is replaceable, so it can be adapted to ropes of different diameters.

[0025] The movable seat 4 has a cutting table 11 on the side facing the rope-releasing mechanism. The cutting table 11 is located below one side of the V-groove. The lifting seat 8 has a lifting lug 12 on the side facing the rope-releasing mechanism. A first hydraulic cylinder 13 is installed on the lifting lug 12. The telescopic end of the first hydraulic cylinder 13 is connected to a lifting block 14. A blade plate 15 is connected to the bottom surface of the lifting block 14 by screws for easy replacement of the blade plate 15. The blade plate 15 is located above the cutting table 11. At least two guide rails 35 are installed on the lifting seat 8 below the lifting lug. A sliding groove 36 is provided on one side of the lifting block 14, and it is slidably connected to the guide rails 35 through the sliding groove 36. The guide rails 35 can guide and stabilize the lifting block, improving the stability of the lifting. By lowering the blade plate 15 and cooperating with the cutting table 11, the carbon fiber rope can be cut. In addition, the frame 2 has a notch 37 to accommodate the passage of the first hydraulic cylinder 13. When the lifting seat 8 is raised or lowered vertically, the first hydraulic cylinder 13 is raised or lowered within the notch 37, thereby preventing the frame 2 from affecting the movement of the first hydraulic cylinder 13.

[0026] The lifting block 14 has an air duct 16 along its long side. The top surface of the lifting block 14 is connected to an air inlet pipe 17 that communicates with the air duct. The bottom of the lifting block 14 has several air outlets 18 that communicate with the air duct, and the air outlets 18 are inclined towards the blade plate 15. The air inlet pipe 17 is connected to an external air compressor (not shown in the attached figure) through a pipe. The air compressor delivers high-pressure gas to the air inlet pipe, which is then sprayed onto the blade plate 15 through the air duct 16 and the air outlets 18, thereby blowing off the broken fibers on the blade plate 15.

[0027] The base 1 is equipped with an anti-rebound mechanism near the frame. This mechanism includes a support base 24, a crossbeam 25, a second hydraulic cylinder 26, and a fixing plate 27. The support base 24 is fixed to the base 1, the crossbeam 25 is connected to one side of the frame 2, and the second hydraulic cylinder 26 is mounted on the crossbeam 25. The extension end of the second hydraulic cylinder 26 is connected to the fixing plate 27, whose bottom surface is serrated. The fixing plate 27 is located above the support base 24. Before cutting, the second hydraulic cylinder 26 is extended, causing the fixing plate 27 to descend, thus pressing the carbon fiber rope tightly against the support base 24. This prevents the rope from rebounding after cutting, facilitating the subsequent pulling of the rope end into the V-groove 7.

[0028] Two guide frames 28 are connected on the base 1 between the rope feeding frame and the support base. Guide rollers 29 are rotatably connected above the two guide frames 28. The two guide rollers 29 are set at different heights, with the height of the guide roller closer to the rope feeding wheel being lower than the height of the guide roller closer to the frame. The carbon fiber rope is guided to the space between the fixed plate 27 and the support base 24 by the two guide rollers 29.

[0029] A control cabinet 38 is provided on one side of the base 1. A PLC controller is installed inside the control cabinet 38. A start button and multiple control buttons are installed on the control cabinet. The first hydraulic cylinder, second hydraulic cylinder, third hydraulic cylinder, geared motor, start button, and control buttons are all electrically connected to the PLC controller. In addition, a hydraulic system is required, which is also electrically connected to the PLC controller. The hydraulic system includes a hydraulic pump, hydraulic valves (directional valves, pressure control valves, flow control valves, etc.), oil pipes, pipelines, filters, coolers, hydraulic oil, etc. Hydraulic oil is used as the working medium. Pressure oil is supplied by the hydraulic pump, controlled by various hydraulic valves, and ultimately output as linear motion by the hydraulic cylinders. This system is a conventional design in this field and will not be described in detail in this application.

[0030] The working principle of this invention is as follows: The carbon fiber ropes are released through the rope release mechanism, and then each rope is placed into the V-groove 7 one by one by manual traction. The second hydraulic cylinder 26 is then extended, causing the fixing plate 27 to descend and press the ropes firmly against the support seat 24, thus initially securing the ropes. Next, the lifting mechanism controls the lowering of the lifting seat 8, causing the pressure plate 9 to descend, and the V-shaped pressure head 10 to descend together, pressing the ropes firmly into the V-groove 7. As the lifting seat descends, the V-shaped pressure head 10 presses down on the movable seat 8, causing the movable seat 8 to sink slightly and compress the compression spring 31, thereby clamping the carbon fiber ropes under slight tension, further preventing uneven cuts caused by rope slack during cutting. Then, the first hydraulic cylinder 13 is extended, causing the lifting block 14 to descend, which in turn causes the blade 15 to descend and cut the rope onto the cutting table 11. During cutting, high-pressure air is sprayed obliquely from the air outlet 18 onto the blade 15, blowing off any remaining fiber debris on the blade 15. After the cutting is completed, the first, second, and third hydraulic cylinders reset, and then the rope releasing mechanism continues to release the rope for the next stage of cutting.
